Lexus RC300 Wheel Fitment Guide (2016-2021)
The Lexus RC300 is one of those cars that looks fast sitting still — and that long hood, wide rear haunches, and aggressive stock fender arches are basically begging for a wheel upgrade. From the factory you're working with 18x8 +45 wheels on a 5x114.3mm bolt pattern with a 60.1mm center bore. Solid, safe, and forgettable. The good news? That +45 leaves plenty of room to dial in a face that actually fills the arches.
The 5x114.3 pattern opens up a massive catalog of wheels, so you're not fighting for options like some of the oddball fitments out there. Whether you want to go square for a clean, balanced look or run a staggered setup to lean into the RWD proportions, the RC300 takes both well. The chassis has the fender clearance and the shape to reward smart offset choices.
We put together six setups we think show off what this platform can do — a mix of square and staggered builds, each with real specs you can actually reference. Dig into the numbers below, see what speaks to the look you're chasing, and build your RC300 the way it should've left the factory.

Want new wheels for your Lexus RC300?
The RC300 rolls out on 18x8 +45 wheels riding a 5x114.3mm bolt pattern — and that bolt pattern is the good news. 5x114.3 is one of the most widely supported fitments out there, so stepping up to 19s or 20s opens the door to serious aftermarket options without hunting for oddball drilling.
Going up to a 19" or 20" diameter is where this coupe really comes alive. We've got fitments across Niche, Velgen, Work, TSW, and Ace Alloy — a mix of square and staggered setups depending on the look you're chasing. Whether you want an aggressive concave face or a clean flush stance, there's a spec here that suits the RC's proportions.

Basic RC300 fitment info
- Bolt pattern: 5x114.3mm
- Bolt thread: M12 x 1.5
- Center bore: 60.1mm
The stock RC300 rolls on 18x8 +45 wheels wrapped in 235/45R18 tires.
Brake clearance
The RC300 skips the RC F's 6-piston Brembos entirely — it runs floating calipers front and rear, with a 334mm front rotor on 2016-2017 cars. There's no factory big-brake trim on this chassis, so the calipers behind your wheels are modest by sport-coupe standards.
Factory diameters ran 18" (235/45R18) and 19" (235/40R19), and those clear the stock hardware without issue. If you're planning to drop below 18", verify caliper clearance first — the stock brakes set the floor.
Add an aftermarket big brake kit and clearance gets tighter fast; a narrow-spoke wheel can catch a larger caliper, and a thin spacer is the usual fix to gain the few millimeters back. Beyond those confirmed points, I won't guess at rub specs for your exact setup.
19-Inch Setups
The 19-inch setups here run Ace Alloy and Niche in a 19x8.5, covering both square and staggered configs. Two different approaches, both landing on that sweet 19-inch face for the RC300.

| Front | Rear | |
| Wheels | Niche Essen M147 19x8.5 +35 | Niche Essen M147 19x10 +40 |
| Tires | 245/40/19 | 285/35/19 |
| Notes | RSR Springs w/ GMG alignment | |
This RC300 has the kind of staggered setup that just looks right. The Niche Essen M147 19x8.5 +35 up front on 245/40/19 keeps things tidy, while the wider Niche Essen M147 19x10 +40 on 285/35/19 gives the rear real presence.
RSR springs drop it into the sweet spot and the GMG alignment ties it all together. Clean, planted, and exactly how a coupe like this should sit.

| Tires | 235/40/19 | 235/40/19 |
| Notes | Stock | |
The Ace Alloy Mesh 7 19x8.5 +35 gives this RC300 a clean, balanced look — running the same setup on all four corners keeps everything uniform and purposeful. That mesh face suits the RC's sharp lines perfectly.
Wrapped in 235/40/19 at every corner, the proportions stay tidy on stock suspension. It's the kind of understated square fitment that just works — no drama, just a well-dressed coupe.
20-Inch Staggered Setups
Staggered is where the RC300 really comes alive, and these four builds run the gap between 20x8.5 up front and 20x9 out back. Niche, TSW, Work, and Velgen all bring their own flavor to the same proven staggered formula.

| Front | Rear | |
| Wheels | Work Wheels Zeast ST1 20x9 +38 | Work Wheels Zeast ST1 20x10.5 +45 |
| Tires | 245/35/20 | 245/35/20 |
| Notes | Stock | |
The RC300 already has aggressive lines, and the Work Wheels Zeast ST1 20x9 +38 up front sharpens the whole face. Out back, the Work Wheels Zeast ST1 20x10.5 +45 adds the width this staggered setup lives for, and the extra 1.5 inches genuinely reads at the rear.
Running 245/35/20 front and 245/35/20 rear on stock suspension keeps it clean and honest. No drama, just Work's craftsmanship doing the talking.

| Tires | 245/35/20 | 285/30/20 |
| Notes | Stock | |
The staggered setup here is doing exactly what it should on the RC300. Up front the TSW Bathurst 20x8.5 +40 wrapped in 245/35/20 keeps the nose tidy, while the rear TSW Bathurst 20x10 +40 on 285/30/20 gives the back end that planted, wider-than-front look.
Both corners run +40, so the whole stance stays clean and consistent on the stock suspension. That extra width and meatier rubber out back is the detail that sells it.

| Wheels | Velgen VMB7 20x9 +32 | Velgen VMB7 20x10.5 +45 |
| Tires | 245/35/20 | 285/30/20 |
| Notes | Stock | |
This RC300 nails the aggressive-but-clean look with a proper staggered setup. The Velgen VMB7 20x9 +32 up front on 245/35/20 keeps the nose tidy, while the Velgen VMB7 20x10.5 +45 wrapped in 285/30/20 gives the rear that meatier, planted look.
Riding on stock suspension, it keeps the factory ride height but that wider rear wheel and tire combo does the heavy lifting on the stance. It's a tasteful, functional look that suits the RC's lines perfectly.

| Wheels | Niche Apex 20x8.5 +35 | Niche Apex 20x10 +40 |
| Tires | 245/30/20 | 275/30/20 |
| Notes | Stock | |
The Niche Apex gives this RC300 a clean, purposeful look, and the staggered setup does it right. Up front the Niche Apex 20x8.5 +35 on 245/30/20 keeps things tidy, while the rear Niche Apex 20x10 +40 wrapped in 275/30/20 plants a wider, meaner footprint.
On stock suspension it keeps a factory ride height, but the width difference front to rear gives it that proper rear-biased attitude without trying too hard.
Final Thoughts on Lexus RC300 Fitment
Final Thoughts
Six builds in, the RC300 shows you don't need to chase extremes to make this chassis look right. Everything here lived in the +32 to +40 window on 19s and 20s, and that's the sweet spot for a car with these fender lines. The 19x8.5 setup showed up the most across these builds, and it's an easy one to recommend if you want a wheel that fills the arch without asking too much of you.
The mix of square and staggered setups here tells you there's no single "correct" answer — some of these builds ran even widths front to rear for a clean, uniform look, while others went staggered to add rear presence. Both work on the 5x114.3 platform, and the offsets stayed conservative enough across all six that the face sits where you'd want it. If you're deciding, a square 19x8.5 at the higher end of the +32 to +40 range is the low-drama starting point; go staggered if you want more visual weight out back.
Whichever direction you lean, the brands featured in this guide are all in stock at ThreePiece.us — so once you've settled on a diameter and offset, you can spec it out and have it shipped without hunting around.
